Subject: [dpdk-dev] [PATCH v2 7/8] net/mlx5: add GENEVE TLV option flow translation
Date: Tue, 5 Jan 2021 19:53:56 +0200 [thread overview]
Message-ID: <20210105175358.16712-8-shirik@nvidia.com> (raw)
In-Reply-To: <20210105175358.16712-1-shirik@nvidia.com>
The GENEVE TLV option matching flows must be created
using a translation function.
This function checks whether we already created a Devx
object for the matching and either creates the objects
or updates the reference counter.
